When entering a disaster zone, the first things relief workers do is make sure people have clean water, food, shelter, rest, etc. because those things are the basic things human beings need to stay alive.
We have to have enough food, water, air, rest, etc. before we can live, let alone go on to work, produce, create, innovate, enjoy our lives, and reach our full potential. See Maslow’s Hierarchy of Needs below.
